Analysis of acoustic design Sony MDR-Z1000

The Sony MDR-Z1000 headphones are made with closed-type acoustic design.

Due to the closed type the headphones have passive noise isolation and for the surrounding public the headphones play much quiet than for the listener. External sounds for the listener is on the same quiet level.

Headphones with noise isolation are good for home, when you need not to disturb others while listening to music. It's good in a noisy office, allowing you not to be distracted. In noisy transport playing music in such headphones is more safe for hearing, because due to noise isolation it is possible to listen to music at an average or quiet volume. In the studio, when recording vocals or instruments on a microphone, the closed headphones fit best; Sound from the "minus" of the headphones will not get into the microphone.

Headphones with noise isolation are dangerous to use on the street with active traffic.

Analysis of the sensitivity of Sony MDR-Z1000 headphones


The sensitivity of the Sony MDR-Z1000 headphones is 116.28 dB/V SPL by the voltage and 100.69 dB/mW SPL by the power. The sensitivity by voltage reflects the relative "loudness" of the headphones among others - the higher is the value, the louder are the headphones. The sensitivity by power reflects the efficiency of the headphones. High sensitivity of the headphones means less energy need from the source (for portable devices - less power from the battery).

Depending on the sensitivity, headphones are best to use with sources of optimum power. If the source is too powerful, then there is a high probability of constantly hearing background noise. If source power is weak, there will be insufficient volume level.

In a quiet environment for the Sony MDR-Z1000, an amplifier with a voltage level of at least -12.28 dBV at 28 Ohms is recommended for listening to music with a level of 90 dB SPL (without noise isolation). An amplifier with a level above 25.72 dBV is not desirable if the volume control is digital, not analog.

For noisy environments, an amplifier with a voltage level of at least -0.28 dBV at a load of 27.59 ohms is desirable.


If you want to listen to music at a different volume level, you just need to add or subtract a change in dB to 90 dB SPL (for example, for a desired level of 105 dB SPL, add 15 dB and the minimum voltage level for the amplifier is -12.28 dBV + 15 dB = 2.72 dBV).


Analysis of the impedance of Sony MDR-Z1000 headphones

The average resistance at the headphones Sony MDR-Z1000 is 27.59 Ohm.

The resistance affects the amount of current that the amplifier should give to the headphones. If the current is not enough, the sound quality will deteriorate, beginning with harsh in the sound and ending with a crackling. In most cases, at low current values, the amplifiers operate in comparable quality to class A, and as the current level rises, the quality decreases toward AB, B, and the clipping zone.

Imagine that you have a water tank, which gradually fills with water. The voltage from the amplifier this is the pressure with which the pump draws water from the reservoir. If the inflow of water in the tank is lower than the volume that the pump pumps out, then at the pump outlet we collect water and "bubbles". Similarly will be with the sound from the headphones, which are lacked the current from the amplifier.

For a quiet environment, an amplifier with an output current level of at least 8.81 mA in a given class of quality is desirable (preferably orientated to comparable class A) and 35.09 mA for loud.

Measurements of Sony MDR-Z1000 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Sony MDR-Z1000 test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.
